Impressive! In the past (nine years), I've ran several DSS CF driveshafts on my M6 TT car, each with different rear carriers (ZL1 and 9"). Only issue I had was spinning the driveshaft due to improperly cured epoxy but DSS quickly remedied that. I drove it rain or shine, winter and summer, daily and racecar. I know they had some changes in the recent past so I wonder if quality has slipped. Buddy still has one his 1000whp plus SC M6 and no failure over same long time period. They're supposed to be balanced at something like 10k RPM but I do believe I had some vibration from it.
